To allied-om 'it 'may concern.'

Be it .known that i, Joins aises, a suhiee't of theling et' GreatBritain, and resident of Tiictoria, in the Frovince ot British Columbiaand Dominion oi Canada, have invented a n.y and lniproved 'ianol-lamnrner, which the following is a full, clear, and exact "iption 'lnis .inv

ion relates to'pian'o hammers, and more par cularly such. as have headsprovided .3h adjustable means tor removally mounting the felt stripsused in striking the Wires.

in obiect ot' "tte invention is to provide a device of the classdescribed, having a head resiliently supported on the hammer shank,thereby causing' more decided blow to he struck, and at the saine timepermittinglof a quicker rebound than in the ordinary piano hammer.

further object of the invention is to pro vide a no hammer havingadiustahle means for removably incur ting the telt strip, thus allowingdifferent materials for producing ditierent effects and tones, to heeasily substituted.

'l he invention consists in the construction and combination of parts tohe more full;7 described hereinafter and particularly set fort-h in theclaims.

Reference is to be had to the accompanying drawings forming a part ofthis speciii-v cation, in which similar characters ot' referenceindicate corresponding parts in all the views, and in which Ligure l isa side elevation ot the invention; FivzZ is a cross section on the linel2`2 Fig. i, .and Fig'. 3 is side elevation of a Inodiiication of thedevice, the liller hein oin""ted.

tiefere proceeding to niore detailed dei scription ot' my invention, itshould be understood that l provide a piano hammer having a headresiliently mounted on the herinner shank, and which has adjustableineens to permit otl the removal of the telt strip used in striking thepiano Wires the felt strip being adiustahly hold 'in position, can heeasily shifted when the striking surface hecomes worn out, so thatafresh surface will'` 'he presented tor striking` the Wires. F urther,as the feltstrips are easily removable, other strips olZ dill -entmaterial can be substituted to prodvr different tones,

hammer hack stop l, a hammer butt 2, herinner shanli 3, and a hammerhead 4l. The latter has a hase 5 preferably integral With the hammershank 3, in which openings G are located. .Arranged Within these opereings are supports 7, having their upper ends .laterally disposed to formiingers S. Blocks 9 and l0 respectively have openings at their sides, inwhich the iingers 8 ofi the supports 7 are arranged. l'lhe rear supports7 extend to the rear bloei; l0, the forward supports extending; to theforward block 9, the openings 6 being arranged at angles with each otherfor this purpose. rl`he clock 10 presents a tapered, curved surface atone end, t e other end heling substantially straight. lhe lolocli 9 issomewhat larger than the block 10, and presents a tace substantiallyparalisi to the hloclr -iO at the tace adiaceut thereto. Arrangedbetween these blocks and having one end 12 arranged within an opening.i3 in the block l0, and having it other ond le. suitably threaded toengage a similarly threaded opening l5 in the block 9, is spreadingscrew 16, having a manual grip 18 at the center thereof. This screw ispreferably constructed of aluminum or other suitable material. A pin 19is located on the end l2 of the sereW and serves to engage 'grooves 2Oin the block 10, so that the screw 'will he held against rotation afterthe blocks have been adjust-ed in position. of ,some suitable material,such as felt or'. the like, and presenting a rounded surface at itsouter end, is arranged adjacent to the 'iront face ot' the hloclr Q,which face is tapered so that' it tends to spread the filler as it isas: justed. Encornpassing the iiiler 'and 'the blocks is an adjustableendless strip, pret`- erahly composed. of an outer and inner felt 23 and2e, respectively.

In the operation of my 9 and l0 are adjusted device, the blocks andfirmly hold the telt strip 1n position.. When it isl necessary to removethe latter, the screv'isrotated so that the blocks Aare approached, andthe strip released. The supports 7 are then Withdrawn from the openingsEl in the blocks,- and the strip can then he easily' talrenl troni thesame. As shown moet clearly in Figi, the ports '.7 more deci ed blow ispossih aand at the encjv oi the",T are et as supports is incr erstere?eonstro ed so th mea or t? A filler 21,.

by ine-ans ofi the. spreading screwx so that they are forced apa-rtsametime the resilithe like, a quicker rebound after the blovs?` has beenstruck is produced. The felt strip being easily adjustable, can beshifted so that When the striking surface becomes` Worn a new surface ispresented for striking tlie wires.

lt should be noted my hammer iiller Z1 may be emitted, felt stripcovering the blocks, clearly in Fig. 3.

Having tb us described my invention, what claim as new and desire tosecure by Letters Patentis:

saving only the as shown most 1. In a device of the class described, a v

hammer shank, and. ahead carried thereby,

that the hammers in l one another,

blocks, and a strip arranged about said. the piano are of differentsizes and that in f'iiller and said blocks.

for producingtreble notes the si. in a device of the class described, ahammer shank, pairs of supports carried by said l: animer shank, a blockarranged between tine ends of said supports of eacli pair, means formoving said supports relative to a iiller at the end of one et' said 5.ln a piano hammer, a hammer shank, a base integral therewith, pairs oisupports irremovably carried by said base, said supports lhaving theirupper ends laterally disposed, blocks having openings on their adjacentsides and mounted between said laterally1 disposed ends, a spreadingmember said head comprising relatively adjustable blocks, and a feltband niovably encompassing said blocks. A

2. .In a device et the class described, a

hammer shank, resilient supports carried by said hammer shank, blocksarranged at tine i member is operated to loosen said blocks,

ends of said supports, a felt carried by said blocks, and means foradjusting said blocks with respect to one another;

3. In a device et the class described, a hammer shank, pairs ot supportsarranged upon said hammer shank, blocks removably arranged between theends of said supports i oi eacii pair, a felt carried by said blocks,

and means for adjusting said blocks.

having its ends arranged Within said open Lgs el" said blocks, one ofthe ends of said member being tiireaded, whereby it serves for trieadjustment of said blocks with respect to one another, a l'ront of oneof said blocks, and an endless felt strip arranged about said iiller andsaid blocks and adjustable when said spreading said blocks serving totighten said strip.

In testimony whereof I have signed my name to tizis specification in thepresence of two subscribing Witnesses.
